Rider fit: reaching the ground
The MZ Mastiff 660 has a 831 mm seat; the Suzuki DR125SM sits at 836 mm — a 5 mm difference. As a rule of thumb you flat-foot a bike when your inseam roughly matches its seat height: about 83 cm for the MZ Mastiff 660 and 84 cm for the Suzuki DR125SM.
That makes the MZ Mastiff 660 the easier reach to the ground — the safer pick for shorter riders or anyone who wants both feet planted at a stop — while the Suzuki DR125SM gives taller riders more legroom and a more open knee bend. Load your own height and inseam into the simulator to see exactly how each one fits you.
